Direct estimates of nitrogen abundance for Seyfert 2 nuclei

OL Dors, MV Cardaci, GF Hägele… - Monthly Notices of …, 2024 - academic.oup.com
We derive the nitrogen and oxygen abundances in the narrow line regions (NLRs) of a
sample of 38 local () Seyfert 2 nuclei. For that, we consider narrow optical emission line …

Cosmic Ray Ionization of Low-Excitation Lines in Active Galactic Nuclei and Starburst Galaxies
